AUTOMATIC PAPER-BOX-TOPPING MACHINE.

Application led J u1y 22, 1912. Serial No. 711,001.

T0 all whom t may concern Be it known that I, EDWIN Gr. STAUDE, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Improvements in Automatic Paper-BoX-Topping Machines, of which the following is a specification.

The primary object of my invention is to provide a machine which will automatically paste plain or printed sheets or labels on paper box covers and the like.

A further object is to provide a machine l which can be quickly adjusted for different sizes of work.

Afurther object is to provide a machine `-of simple construction which can be easily kept in order and will require but little eX perience to operate.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification, Figure 1 shows the plan view of the automatic'topping machine v embodying my invention, Fig. 2 is a vertical section thereof, Fig. 3 is a cross section on' the line w-- of Fig. 2, 'looking in the direction of the arrow, Fig. 4 is an enlarged sectional view of the rear portion of the machine, Fig. 5 is an elevation of the sheet or label and work receiving cylinders, Fig. 6 is an end view, partially in section, of the cylinders, showing a cover passing between them. ,v

In the drawing, 2 represents a suitable frame in vwhich the operating mechanism of the'machine -is mounted. The side rails of said frame on one side of the machine are provided with inwardly projecting lugs 3 and 4, preferably integral with the frame, having bearings for upright screw shafts 5. (See Figs. 2.and 3.) On these screw shafts yokes 7 and 8 are Amounted and arranged to project into the space-between the side rails of the frame, as shown in Fig. 3, and having bearings for parallel, transverse shafts 9 and 10. (See Fig. 2.) rllhese yokes and shafts are adjusted vertically on the upright screws by means of the operating wheels 11 and 12. The upright screw shafts `5 are connected by a sprocket chain 13 which passes vover suitable sprockets secured to s aidupright shafts and by revolving either of the hand wheels 11 or 12 the upright screw shafts will be op- Speeication of Letters Patent.

Patenten Apr. e, 1915.

,erated simultaneously to raise or lower th adjustable guides 19 are provided at the sides of the hopper for holding the boX covers-or other work in proper position on the supporting plate 17". The yokes 7 and 8 are preferably connected with one another by horizontal parallel rods 20 .and 2l, and between these rods at suitable intervals I provide cross shafts 22, 23, 24 and 25. Brackets 26 and 27 are mounted on the cross shafts 23 and 24 and support angle bars 28 and 29. The horizontal flanges of these angle bars serve as a table or way over which the work is fed and the vertical flanges of said bars form sidevguides for the work. The brackets are adjusted transversely of the machine on the shafts 23 and 24by suitable clamp devices 30, by means of which-the distance between the angle bars 28 and' 29 may be varied to accommodate dierent widths of box covers or other materialthat is fed through the machine. the shafts '22 and 25 and are connected to one another by a rod 33 and support a channel bar 34 located intermediate to the brackets 26 and 27. (See Figs. 2 and 3.) The ends of the channelbar 34 are curved downwardly and fit into annulargrooves in the hubs of the sprockets 14 and 15, thereby Brackets 32 are mounted on holding the channel bar in line with the 37 and 38. This receiving member 36 is I preferably constructed as follows: The sections 37 are keyed to the shaft 35 andthe sections 38 are free to turn thereon and yhave a portion thereof cut away to allow the key of the section 37 to be made inthe form of a continuous bar and hold all parts of the sec-v tions 37 on theshaft 35 while permitting the adjustment of the sections 38'. The section v 38 has teeth 39 near its hub, meshing with a section 37. Theperipheral area of the sections 37 and 38 is substantially the same and the section 38 may be rotated in one direcf ltion to 'register or coincide with the sections 37 or in the opposite direction to separate the sections and provide a peripheral surface equal to the combined peripheral area of both sections. (See Fig. 4.) The section 37 has a toe `or point 41 that is adapted to engage the forward flange of a box cover and feed the cover forward between the part 37 and the labelreceiving cylinder or member above. The rotary adjustment of the lpart 38 is easily and quickly accomplished through the medium of the pinion 40, which has a squared end to receive an operating tool. (See Figs. 4, 5 and 6.) The plate 1S is spaced from the ways beneath a sucient distance to allow a cover to be fed out from the bottom of the pile in the hopper upon the engagementof one of the feed pins with the forward flange of the cover, as indicated in Figs. 2 and 3, upon the engagement of` a pin with the cover to be fed forward upon the angle bars 28 and 29 to the sheet or labeli applying mechanism, which T will ceed to describe in detail.

Above the feeding mechanism for the covers I arrange a feed wheel 42 in lposition to-engage and feed a sheet or label from the hopper 43. A' drum 44 is located beneath the wheel 42 and has belts 45 and an idle roll 46. The movement of the wheel 42 operates lto feed a sheet or label between it and the drum 44.

47 is a shaft mounted in suitable' bearings and having sprockets 48 over which chains 49 operate. An idler 50 is arranged to take up the slack of the chain and the wear of the machine. Pins 51 are mounted on the sprocket chains 49. i

The wheel 42f.is arranged to draw one sheet or-label from the hopper -with each revolution and deliver it to the belts 45, which operate at a greater speed than the pins 51 so that the forward edge 4of the sheet or label will strike-the pins 51 and be 'held in contact therewithas-the said pins move toward the rear of the machine. The

movement of the pins is timed to allow thesheets Vor labels to pass between` the feed rolls 51 on the shaft 47 and ro1ls452 on a shaft 53 arranged above the shaft 47. When the sheet or label passes between these rolls it will be fed forward positively between them into contact with a curved (leflector 54, which operates tobend the forward nieatea portion of the' sheet or label downwardly, upon the gumming roll 55.' This roll 55 operates in a suitable receptacle 56 which is adapted, to contain an adhesive agent in liquid formvfor application to'the surface of the gumming roll.

T prefer to provide strippersV 57, preferably of wire, located near the deflector 54 and operating to stri the sheets or labels from the gumming ro l and near. these strippers is a sheet or label receiving cylinder 58 revolving with the shaft 59 and having a gripper devicel 60 to grasp-the forward end of the sheet or label and draw it against the surface of the cylinder 58 and move it downwardly for application to the work.

The gripper device isv operated by a suitable cam mechanism 61, which is adjustably secured to the frame of the machine, concentric with the shaft 59. The spring 62 holds the gripper device in yielding contact with the cam 61. The cam 61 is cut away at the point 63 to open the gripper just prior to thetime that the work and the sheet or label pass the center line between the two cylinders. This gripper device may be modified in various ways and any other suitable equivalent mechanism may be employed in place 'of1 it to grasp the sheet or label and feed it forwardly into registering relation with the box cover. The sheet or label being drawn toward-the periphery of the cylinder 58 and the covers or other -materialbeing fed forward, the sheet or label will be applied to the flat upper sur-- face of the cover as the sheet or label and 'the ycover pass between the rolls, the side to permit easy access tothe work cylinder for adjusting purposes.`

A separator device 66, (see Figs. and 6) I is arranged between the sections 37 and 38 to provide space for the side Hanges of the cover. Anl adjusting nut 67 is arranged to bear against the head 36 of the work cylinder to clamp the sections vof the cylinder ,against a second head 68 that is secured on the shaft by means of a set screw 68. This head 68 will remain stationary'and lateral adjustment of the sections will be accomplished by releasing the nut 67 and arranging the separator or spacer between the sections to separate them suiiciently to receive the side anges of th'e cover. The shaft 47 and the-roll 55 have a driving connection 47 with the shaft 35, as illustrated in Fig.

1. VThe shaft'35 extends outwardly beyond lill@ A The sheet that-isaxed .by this machine to the box cover may 'be either plain or printed. In the latter case it will'beI ap-` propriately designated as a label. The operation of `the machine is, of course, the same, .whether the sheet that is .aliixed .to `the box cover or other article is plain 'or has .inscriptions thereon.' 'While the sheets are usually of paper it isobvious that they may be of cloth lor other suitable, flexible material. The Asheets andthe articles to lwhich they may he affixed may be of any suitable size within the range of .adjustment of the machine.
